Giant Defy is an endurance bike that has been around for years and with each one, it's received some added improvements that have made it even better. The 2024 Advanced SL 0 we tested convinced us of being an exceptional endurance road bike that combines comfort, speed, and practicality. While this model comes with a high price tag of £11,499, it also offers a top-tier riding experience.
The bike boasts an excellent frameset, lightweight construction, and a high-end spec to complete it. It rolls on 32mm (measured at 34.2mm) Cadex Classic tubeless tyres that are wide, but hence for a road bike but offer a comfortable and smooth ride.
Giant has focused on simplicity rather than gimmicks for comfort, with features like dropped seat stays and a flexible D-Fuse seatpost. The new Contact SLR handlebar also contributes to a vibration-free ride. However, Giant has tweaked the geometry, making the bike more performance-oriented by lowering the front end, which adds to the sporty feel without compromising comfort.
Despite its endurance focus, the Defy Advanced SL 0 is impressively light and accelerates well, and shifting is crips thanks to the 12-speed SRAM Red eTap AXS groupset. The Defy Advanced SL 0 is a standout endurance bike, but for better value, exploring the lower-tier models such as the Giant Defy Advanced 1 we've also rated highly may be more appealing for most.
